1 Claim.

This application relates to apparatus for tumbling and washing steel barrels or drums and aims particularly to provide an improved tumbling and washing machine.

For an understanding of my tumbler and Washer, reference may be had to the appended drawings. In these drawings,

Fig. 1 is a cut-away elevation view of the machine;

Figs. 2, 3 and 5 are sectional views of the same on lines 2-2, 33, and 5-5 of Fig. 1;

Fig. 4 is an end View of the machine, part being cut away.

The machine shown comprises an open top tank IIJ, the upper part of whose front is open as indicated. Journalled in bearings formed in the end walls of the tank are axially aligned stub shafts II connected to, connected by, and supporting a cradle I2 generally of semi-circular cross section so as to be capable of receiving therein a barrel or drum I4 to be washed and tumbled, The cradle is so formed and connected to the stub shafts that the longitudinal central axis of the cradle is on a bias with respect to the axes of the stub shafts II, whereby proper rotation of the stub shafts by a suitable driving means, later to be described, causes constant rotation of the cradle and constant tumbling of a barrel contained therein through the washing s0- lution within the tank, which solution is maintained at high temperature by the steam coil heater generally referenced I5.

The cradle is so .proportioned that it is considerably longer than the drums intended to be disposed therein, whereby such drums, held in place in the cradle by the detachable chain fasteners I6, may shift longitudinally in the cradle to a limited extent, the amount of shifting, as determined by the relative engagement of the chains I6 and the beads I1 of the drums, being insufficient topermit the drums to bump against the ends of the cradle. The cradle is of greater diameter than the drums, whereby the drums can rotate freely in the cradle as the cradle itself is rotated, such rotation of the drums with respect to the cradle as the cradle rotates being effective in the tumbling and Washing of the drums, it being understood that when the drums are disposed within the cradle, they have their bungs open and that suitable abraders, such as short lengths of chain are within the drums to` scrape against the interiors of the drums and scrape 01T the paint and other coatings on the interiors of the drums.

It has been discovered that the following relative dimensions have proven satisfactory: for drums 32 in. long and 22 in. in diameter, a cradle 40 in. long and 27 in. in diameter has' been used, and the center line of the stub shafts I I was 6 in. away from the center line of the cradle itself, such measurements being taken at the ends of the cradle.

In front of the tank there is disposed a sturdy and rigidly mounted apron I8 which receives the drip from drums being removed from the tank, and such drip returns to the tank through the holes at I9 near the bottom of the trough 20 provided by the apron.

One of the stub shafts is formed to project through the end wall of the tank a considerable distance and is coupled by a chain and sprocket arrangement 20 to a speed reducing gear box 2I connected to a motor 22. The entire driving means, comprising parts 2Il--2I-22, is disposed Within a sealed compartment generally referenced 23 whose end or side is removable from the rest of the compartment to expose the drive means for lubrication, inspection and repair. The drive means is so positioned relative to the tank that it is completely sealed from the interior of the tank. In addition, the motor and speed reducer are positioned directly above the upper flanged edge of the adjacent tank end, whereby the weight of the motor and speed reducer is distributed throughout the tank end, the latter acting as a column support for the drive parts.. This method of mounting the drive means, predicated upo-n the disposition of the heavy parts of the drive means directly above the end of the tank, has proven extremely satisfactory and has eliminated considerable of the difficulty that would have been encountered were the drive means mounted on brackets formed as cantilevers projecting end- Wise from an end of the tank.

When the machine is to be used, the operator rst arranges that the cradle shall be at rest with its open side at the top of the cradle to permit loading and unloading therein of drums. Drums fastened within the cradle by means of the detachable fastener chains, and containing chain abraders, revolve along with and also with respect to the revolving cradle, and also shift longitudinally of the cradle during the Washing and tumbling action, with the result that effective tumbling and washing of the drums take place. Injury to the cradle by the drums bumping against the cradle at the ends is prevented by the engagement of the drum holding chains with the beads on the drums.

Now having described the drum tumbling and Washing apparatus herein disclosed, reference Will be had to the claim which follows for a determination of the invention.

I claim:

In combination, a tank, a cradle therein having a stub shaft projecting therefrom and journalled in an end of the tank and projecting through such tank end, and driving means outside the tank and connected toy such stub shaft 10 end outside the tank, the driving means including
